C11G (Rev.7.1) User Manual

•Built-in Variable Speed Control.
It has an optoisolated analog 0-
10VDC output that will convert a step
signal into an analog signal that can
be used to command a commercial
VFD. This analog can be adjusted
using on-board potentiometer, so this
board can be adjusted to other
voltages.
•Two Solid State Relay with NO and
NC positions.
Mechanical relays are very flexible
because they can be used for AC or
DC and come with NO and NC
(Normally Open and Normally
Closed) positions.
•Status LEDs on all inputs and
output connections.
No more guessing. You can SEE all
your signals. Save valuable time and
brainpower for CNCing. To avoid
remaining current to the main load
(driver or other device), all the
indicator LEDs are driven by
independent buffers of the ones that
drive de output.
•Output pins 1, 2, 3, 4, 5, 6, 7, 8, 9,
14, 16, 17.
•Input pins 10, 11, 12, 13, 15.
•Input and output pins with close
by ground or +5vdc connections
•The common terminal to pins 2-9
can be ground or +5vdc. Forget
about grounding problems. Easily
connect your pin by using your close
by ground connection. No need to be
an electronics expert to ground all
your stuff. The board has a jumper
that allows you to select if the
common terminal to pins 2-9 will
carry a ground or +5vdc. So if you
are connecting encoders or proximity
switches, you can select it to ground.
If you are connecting Geckodrives or
limit switches, you can set It to be
+5VDC.
•External Enable Pin (EN). The
board has a pin that allows you to
enable/disable all the outputs at
once. The board requires +5vdc in
the EN pin. If it is not present, it will
send all the outputs to ground. You
can use this to enable or disable the
system manually, or you can install
an external Safety Charge Pump or
other external safety monitoring
device.
•Works directly with popular CNC
hardware and software. Such as
Geckodrive, DeskCNC or Rutex, and
parallel port control software, such
as mach2, Linux EMC, TurboCNC,
CNCPlayer, CNCZeus and others.
(Not all tested).
•All TTL 5VDC signals. Interface
directly with parallel port interface
products and other CNC4PC cards.
5VDC (TTL) cards are very common
among automation devices.
•Screw-On connections for all
terminals. You only have to screw-
on the wires to make all your
connections.
•All pins can be used in a
concurrent manner.
You can use all the input or output
pins in a concurrent manner. For
